DOOR.

Specification of Letters Patent.

Patented .Tune 12, 1906.

Application led November 8, 1905. Serial No. 286.407.

To all who'm, it may concern,.-

Be it known that we, JOSEPH A. MEYER and JOSEPH S. SATTER, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Doors, which improvement is fully set forth in the following specification and shownin the accompanying drawings.

Our invention is an improved door for conveniently closing doorways'or openings leading into apartments or inclosures generally, it being designed more particularly to be used to cars. Doors for this purpose need to close thr1 associated openings tightly, making airtig t veniently effected with an ordinary sliding door, and the hinged door in common use is clumsy and further objectionable, as: when swung out from the side of the car it is much in the way and a source of danger, especially when passing through tunnels.

' We have aimed in our present invention to improve upon the doors now-in use upon the *E sides ofrefrigerator and other freight or box cars.

jgThe objects and advantages of theinvention will be brought out and made to appear in the following specification and the construction particularly pointed out in the appended claims,'reference beinghad to the accompanying drawings, which, with the reference characters marked thereon, form a part of this specification.

Figure 1 is a side elevation of a part of the wall of a car or other inclosure, showing our improved door in place thereon, parts being shown in-two positions by full and by dotted lines, with parts broken away. Fig. 2 is a y. liorizontal section of parts, taken on the brokenI dotted line 2 2 in Fi 1', parts being shown 1n two positions by fu l and by dotted lines. Fig. 3 is a verticalsection on the dotted lines 3 3 in Figs. 1 and 2, partsfbeing broken away. Fig. 4 is a front elevation of a part of the door, more fully showing in detail the form and arrangement of parta-parts being broken away and omitted.-TFig. 5 is a vertical section of parts of the door and associated parts on the dotted line 5 5 in Fig. 4, parts being broken away. Fig. 6 is a plan of a carryingsarm and some associated parts seen as in ig. 2. Fig. 7 is a plan of some of the parts shown in Fig. 6 occu ying different relative-positions. Fig. Sis alhorizontal section of a part of the door and some associated close the doorways of refrigerator- C joints all round, which cannot be conparts, taken on the dotted line 8 in Fig. 1, parts being broken away. Fig. 9 is a side elevation of some of the mechanism supporting the door, seen as indicated by arrow 9vin Fig. 6, parts being broken away. Figs. 6 to 9, inclusive, are drawn to a scale twice 'that 1 of the other iigures../

Referring to the parts shown in the drawings, A, Figs. 1, 2, and 3, represents a porfreight or refrigerator car. B is an openin f or doorway through the wall or side A, an

our improved door to fill and close the openin B. The door C is supported and I:the lower truck being in vertical lines beneath the two standards of the upper truck. These standards are a short distance outside lof the two tracks E E and carry or hold the wheels a., as shown.

The door C is provided with a series of four lvertical brackets din upper and lower pairs, l.the brackets of the upper pair projectin slightly above the upper edge of the door an @those of the lower* air projecting similarly `below the lower edge of the door. These brackets are each formed with a laterally-expanded part or head c, Fi s. 1, 3, and 9, at its l proj ecting end, each head aving a longitudi- Inally-projecting center pin e, the ins of the upper brackets ointing vertical y upward tically downward. Likewise t e standards b are formed with longitudinally-projecting pins f, Figs. 1, 3, 6, and 9, similar to the center pins e, the pins of the two up er standards being at the lower ends of the atter and pointing downward and those of the lower standards bein at their upper ends and ointing upwar The standards b and the lugs d occupy such relative positions that the tal p ane, ikewise the four pins below the door, all the pins being connected in pairs by carrying-arms g, Figs. 1, 2, 3, 6, and 9 These carrying-arms are all of the same length and alike, each being pivotally connected with the parts at either end, which admits of the ,posts or standards b b, the two standards ofl tion of a wall of an inclosure, as the side of a j control ed by means involving upper and vif and those of the ower brackets 1pointing ver- IOO IIO

:o5l four ins e above the door are in a horizonspective studs h, so the said arms may freely turn on the respective center pins e when the door is swun as above stated. The parts or shoulders of the arms terminating the left ends of the respective recesses i meeting the adjacent studs h constitute collectively a sto for the swinging or circular motion of the oor C when moving outward from the opening B, holding it inthe position indicated by dotted lines in Fig. 2. When thus swung outward to o en the car, the door is in position to be rol ed or moved laterally along the osition shown by full lines in the figure, al positions ofthe doorv being arallel with one another and with the side o the car or wall A. The length of the carryin -arms g is such and the stop-stud L so relative y laced that the door can in no case f om the adjacent part of the car, E its extreme or outermost position (shown in 5 tracks E E to the move far Figs. 2 and 3) being only sufiicient to admit of 1ts moving freely edgewise along the tracks without touching the side of the car. The edgewise motions of the door are made parallel With the side of the car, stops g', Fig. 1, on the tracks being provided to arrest the lateral motions of the door in both directions. Fig. 6 shows clearly the shoulder 7c in contact with the stud h, as when the door is swung outward, as stated, the relative positions of the door and the adjacent art of the carrying-arm when the door is c osedl being shown in Fig. 7, the stud being at the opposite end of the recess i.

The opening or doorway B is preferably made with Haring sides, as appears in Figs. 1 and 2, covered with yielding or fibrous strips l for packing, the edges of the door C being similarly slanted at m, where meeting the said -fibrous strips. The door is further formed with rectangular outer and inner parts n o, Figs. 2, 3, 6, and 8, to fill correspondingly-formed ortions p 1' of the opening B, a together t e door C when in place forming an air-tight joint with the four sides of the o ning.

The oor C is held in place in its closed osition and controlled by mechanism invo ving a series of latch-bolts s, Figs. 1, 2, 3, and 8, catching under rests or sockets t, secured to the side or wall A adjacent to the respective sides of the opening B. At the middle of the door is placed a short horizontal headed spindle u, (shown more in detail in Figs. 4 and 5,) projecting from the door and adapted to turn in a sleeve v rigid with the door. The outer end of this spindle is squared for a distance for receiving upon it a star-piece or multiple-armed part rw, holding pivotally at the ends of its branches the inner ends of the respective latch-bolts s, as appears in Fig. 1. Outside of the part wis placed a jointed lever 11:, Fi s. 1, 2, 3, and 5, made rigid with the s ind e fu., by means of which the latter, with t e part fw, is turned for .the purpose of moving the series of latch-bolts into engagement with their res ective sockets t or away therefrom, as clear y indicated by the full-line and the dotted-line positions of the parts shown in Fig. l. The side motion of the lever a: for withdrawin the latch-bolts from the sockets is arrested y a sto y rigid with the door, the movements of t 1e latch-bolts being controlled by loops z rigid with the door.

The lever consists of two main parts joined by a hinge a', Figs. 1 and 3, the extreme part b having an o ening c to pass over and receive a stud d?, Figs. 1 and 2, reaching outward from the surface of the door C to hold the lever. This catching of the lever by the stud d serves to lock it in position to hold the latch-bolts sin engagement with the sockets t, thus holding the door securely closed.

We provide with the other parts a curved catch-finger e upon the lever pivoted to the latter in position to have its free end assthrough an opening in the stud d outsi e of the lever to revent the esca e of the latter from the stu d until the catc -inger is withdrawn from the stud. The extreme end of the catch-finger is perforated, as shown at e",

- or otherwise roughened to hold a body of wax for sealing the door.

To cause the door to be firmly Apressed to place when closed, the free ends f Figs. 2 and 8, of the latch-bolts s are tapered, as shown, the adjacent surfaces of the sockets t being correspondingly inclined. This form of the engaging parts causes the door when closed and secured to firmly press the packing- IOO IIO

strips l and form an air-tight joint with the car all round.

To open the car or inclosure, the seal is first broken from the end of the catch-finger e and the latter turned back out of the stud d. The outer part b of the lever is then turned upon the hinge a away from the stud to release the lever, which may be then swung laterally to the osition shown by dotted lines in Fi 1, w ich withdraws the latch-bolts from t e sockets and allows the door to be swung on the trucks D back from the side or body A, when the door may be readily rolled to the right awa from the o ening B, as stated. To a ain c ose the car, t e door is returned to the eft-to the position shown by dotted lines-when it may be again swun into place in the opening B, .tigiese rectilinear rolling motions and 'the swinging or circular motions being distinct from each other and alternated.

What we claim as our invention, and desire to secure by Letters Patent, is-f 1. The combination of a door, upper and lower tracks, upper and lower trucks having Wheels running on said tracks, carrying-arms pivotally connected at one end to the standards of said trucks, the other ends of said arms being formed with circular heads having peripheral recesses and shoulders, verti ca l y-disp'osed brackets on the door at top and bottom and projecting-'beyond the top and bottom ed es of the door, each bracket having a laterally-expanded part at its projecting end with a vertically rojecting stud and an integral vertically-disposed center pin, said pins being engaged in openings in the ends of the carrying-arms and said studs disposed in said eripheral recesses and engaging said shoulder 2. The combination of a door, upper and lower tracks, upper and lower trucks having Wheels running on said tracks, carrying-arms pivotally connected at one end to the standards of said trucks, the other ends of said arms being formed with circular heads having peripheral recesses and shoulders, vertical -disposed brackets on the door at top and bottom and projecting beyond the top 3o and bottom ed es of the door, each bracket having a latera ly-expanded part at its projecting end with a vertically rojecting stud and an integral verticallyisposed center pin, said pins being engaged in openings in 3 5 the ends of the carrying-arms and said studs disposed in said peripheral recesses and engaging said shoulders, and oppositely-dis? posed stops on opposite ends of the tracks, one for engagement with a Wheel ofthe truck 4o and the other for engagement with a standard of the truck for limiting the movement of the door.

In witness whereof we have hereunto set our hands, this 4th day of November, 1905, in 45 the presence of two subscribing witnesses.
